"Downton Abbey" shares new photos from season 5

Last time we checked in with the storied family from the hit British drama, Lady Mary's son, George, and Tom Branson's daughter, Sybbie, were little babies. Now, it seems they're growing up.

"Downton" has released new portraits from the show's upcoming fifth season, set in 1924, showing the new actors playing the two children (Fifi Hart as Sybbie, twins Zac and Oliver Barker as George), newcomer Richard E. Grant as Simon Bricker and some of the show's other returning characters.

You can see Lady Mary, Lord and Lady Grantham, Anna and Mr. Bates, Daisy, Branson and the rest of the group in the photos below.

"Downton Abbey" season 5 premieres in the U.K. this fall, and on PBS in the U.S. on Jan. 4.
